Towards Ultracold Mixture of Lithium and Strontium

Modeling dissolved organic carbon in temperate forest soils:TRIPLEX-DOC model development and validation

第十八届全国量子光学学术会议

作者：马晓彬 z.Ye X.Li z.guo L.You M.K.Tey 清华大学 State Key Laboratory of Low Dimensional Quantum Physics Department of PhysicsTsinghua University Collaborative Innovation Center of Quantum Matter

While bi-alkali-metal quantum mixtures have been produced and studied for about a decade, mixtures of alkali-metal and electron spin-singlet atoms are a more recent development [1–3]. Both lithium and strontium come with bosonic and fermionic isotopes, which will enable many possibilities for rich inter-species interaction dominated mixture physics, and facilitate systematic investigations of impurity and disorder related many body quantum models [4]. Progress towards a new experimental setup aimed at realizing degenerate mixtures of lithium and strontium atoms will be presented.

Even though dissolved organic carbon(DOC) is the most active carbon(C) cycling in soil organic carbon(SOC) pools, it receives little attention from the global C budget. DOC fluxes are critical to aquatic ecosystem inputs and contribute to the C balance of terrestrial ecosystems, but few ecosystem models have attempted to integrate DOC dynamics into terrestrial C cycling. This study introduces a new process-based model, TRIPLEX-DOC, that is capable of estimating DOC dynamics in forest soils by incorporating both ecological drivers and biogeochemical processes. TRIPLEXDOC was developed from Forest-DNDC, a biogeochemical model simulating C and nitrogen(N) dynamics, coupled with a new DOC process module that predicts metabolic transformations,sorption/desorption, and DOC leaching in forest soils. The model was validated against field observations of DOC concentrations and fluxes at white pine forest stands located in southern Ontario, Canada. The model was able to simulate seasonal dynamics of DOC concentrations and the magnitudes observed within different soil layers, as well as DOC leaching in the age sequence of these forests. Additionally,TRIPLEX-DOC estimated the effect of forest harvestingon DOC leaching, with a significant increase following harvesting,illustrating that land use change is of critical importance in regulating DOC leaching in temperate forests as an important source of C input to aquatic ecosystems.

In this study,a two-step method was used to synthesize highly luminescent AgGaS/znS/znS quantum dots(QDs).In the first step,an inner znS shell was formed via a one-pot method,which resulted in a smaller lattice mismatch between the AgGaS core and the outer znS shell,thereby facilitating the formation of a thick outer *** the two-step shelling process,the synthesized AgGaS/znS/znS QDs showed an excellent photoluminescence quantum yield(PLQY)of 96.4%with a peak wavelength of 508 nm,repre-senting the highest PLQY reported thus far for AgGaS ***,the effect of halogen ions in zn precursors on the shelling process was *** was proposed that the capacity of halogen ions to coordinate with the QDs influenced the balance between zn cation diffusion and znS shelling ***,the znS shelling reaction was dominant when znCl_(2)was employed,while zn cation diffusion was the dominant process under the I^(−)-rich *** work provides insights into the interfacial restructuring during the znS shelling and offers a clear map for the tailored synthesis of core/shell QDs.

Given a doubling weightωon the unit disk D,let A_(ω)^(p) be the space of all the holomorphic functions f,where∥f∥A_(ω)^(p):=(∫_(D)|f(z)|_(p)ω(z)dA(z))^(1/p)ze the topological connectedness of the set of composition operators on A_(ω)^(p).As an application,we construct an interesting example which reveals that two composition operators on A_(α)^(p) in the same path component may fail to have a compact difference and give a negative answer to the Shapiro-Sundberg question in the(standard)weighted Bergman *** addition,we completely describe the central compactness of any finite linear combinations of composition operators on A_(ω)^(p) in three terms:a Julia-Carathéodory-type function-theoretic characterization,a power-type characterization,and a Carleson-type measure-theoretic characterization.
